\u201cAppropriate corrective actions have been identified and are currently being developed for implementation. The corrective actions are expected to be complete on the existing flight units in the June\/July time frame in order to support a Zenit launch from Baikonur in the August\/September time frame and do not involve any design changes to the flight hardware,\u201d noted the Board.<\/p>\n
\u201cThe corrective actions focus on additional standalone inspections and testing of the BIM prior installation into the Zenit 1st stage engine compartment\u201d<\/p>\n

Land Launch\u2019s Zenit-3SLB vehicle addresses the launch needs of commercial satellites weighing up to three-and-a-half metric tonnes. The two-stage Zenit-2SLB is also available for lifting payloads up to thirteen metric tonnes to inclined low Earth orbits.<\/p>\n

The Zenit-3SLB launch vehicle represents the Zenit rocket family that uses non-toxic propellants, namely liquid oxygen and kerosene RG-1. It was developed to launch spacecraft from Baikonur Space Center under the Land Launch Program into medium, high circular and elliptic orbits, (including GTO and GSO) as well as to interplanetary orbits.<\/p>\nThe launch vehicle was designed from two-stage Zenit-2SB of Yuzhnoye development and DM-SL upper stage of Energia development to make Zenit-3SLB integrated launch vehicle operated in the composition of Zenit-M space rocket complex.<\/p>\n
The Land Launch configurations are closely derived from the Sea Launch system, in particular via the propulsion systems and all flight critical avionics that are unchanged between the two versions. The fairings represent the most significance difference, with the Zenit-3SLB fairing using an improved version of the heritage Zenit-2 fairing.<\/p>\n

The Zenit 3SLB and DM-SLB Upper Stage \u2013 a variant of the Block DM \u2013 successfully completes its mission that included three burns of the Upper Stage, resulting in spacecraft separation just under six hours after launch.<\/p>\nBuilt by Russia\u2019s Energia Corporation, the Block DM-SLB upper stage is designed to boost satellites to highly elliptical or circular orbits and escape trajectories. The DM-SLB used on the Zenit-3SLB rocket is closely derived from the Sea Launch Block DM-SL. It is a LOX\/kerosene upper stage capable of igniting up to three times during a mission.<\/p>\n
The DM-SLB base structure is comprised of an upper adapter together with an internal truss. The middle and lower adapters that enclose the stage are jettisoned before the first ignition of the Block\u2019s main engine. Kerosene is contained in a toroidal tank connected by a truss to the upper adapter which encircles the turbopump of the 11D58M main engine.<\/p>\n
The spherical LOX tank and the avionics\/payload truss are located above the kerosene tank, and are also connected to the upper adapter. Providing stabilization during coast periods, two attitude control\/ullage engines are located on the bottom of the kerosene tank.<\/p>\n
AMOS-4\u2019s multiple Ku and Ka transponders enable a wide range of cross-band, cross-beam connectivity options.<\/p>\n
The satellite sports two shaped steerable Ku band beams covering Russia and India with optional steering to Southeast Asia, the Middle East, Central Asia, India, South Africa and Central East Europe. It also has one shaped steerable Ka band beam covering the Middle East.<\/p>\n
![\"AMOS-4\"](\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2013\/08\/Z412.jpg\" "\\"AMOS-4\\"")
Optional steering options will include coverage to Russia, India, China, Central Asia, Southeast Asia, and South Africa.<\/p>\n\u201cFor our customers, this means extensive broadcast and broadband reach into the vast urban and rural areas of these regions. Available satellite services for customers include Direct-To-Home (DTH), video distribution, VSAT communications and broadband Internet,\u201d noted the customer, spacecom.<\/p>\n
\u201cWith its new orbital slot, additional capacity, expanded coverage areas and cross-region connectivity, AMOS-4 positions Spacecom at the forefront of international satellite operators delivering comprehensive satellite solutions.<\/p>\n
\u201cOur constellation, which provides comprehensive coverage for Europe, Africa and the Middle East, also includes our AMOS-2 and AMOS-3 satellites, co-located at the 4 degrees W orbital \u201cHot Spot\u201d, and AMOS-5 located at 17 degrees E.\u201d<\/p>\n
